The stone clay dates back to the 1st millennium BC and contains ancient Bronze Age stone graves at the eastern edge of the grove. At the center of the grove, in a 40 x 40 m area, is a megalithic structure built of boulders on an exposed limestone slab. The monument is 3 m high, has a circumference of 55 m, and a diameter of 16 m. It is surrounded by stone circles of varying radii, oriented toward the center.
